/*
 * CharStrings are encoded following the the CharString Encoding sequence
 * describe in Chapter 6 of the "Adobe Type1 Font Format" specification.
 * The value in a byte indicates a command, a number, or subsequent bytes
 * that are to be interpreted in a special way.
 *
 * CharString Number Encoding:
 *  A CharString byte containing the values from 32 through 255 inclusive
 *  indicate an integer. These values are decoded in four ranges.
 *
 * 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
 * indicate the integer v - 139. Thus, the integer values from -107 through
 * 107 inclusive may be encoded in single byte.
 *
 * 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
 * indicates an integer involving the next byte, w, according to the formula:
 * [(v - 247) x 256] + w + 108
 *
 * 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
 * indicates an integer involving the next byte, w, according to the formula:
 * -[(v - 251) * 256] - w - 108
 *
 * 4. A CharString containing the value 255 indicates that the next 4 bytes
 * are a two complement signed integer. The first of these bytes contains the
 * highest order bits, the second byte contains the next higher order bits
 * and the fourth byte contain the lowest order bits.
 *
 *
 * CharString Command Encoding:
 *  CharStrings commands are encoded in 1 or 2 bytes.
 *
 *  Single byte commands are encoded in 1 byte that contains a value between
 *  0 and 31 inclusive.
 *  If a command byte contains the value 12, then the value in the next byte
 *  indicates a command. This "escape" mechanism allows many extra commands
 * to be encoded and this encoding technique helps to minimize the length of
 * the charStrings.
